Famous Quotes & Sayings

Richard P. Feynman

I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. We will not become enthusiastic for the fact, the knowledge, the absolute truth of the day, but remain always uncertain … In order to make progress, one must leave the door to the unknown ajar.

Richard P. Feynman

Unless a thing can be defined by measurement, it has no place in a theory. And since an accurate value of the momentum of a localized particle cannot be defined by measurement it therefore has no place in the theory.

Richard P. Feynman

It is odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo drums, the introducer never seems to find it necessary to mention that I also do theoretical physics.

Richard P. Feynman

Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.

Richard P. Feynman

Scientists are explorers. Philosophers are tourists.

Richard P. Feynman

The difficulty really is psychological and exists in the perpetual torment that results from your saying to yourself, "But how can it be like that?" which is a reflection of uncontrolled but utterly vain desire to see it in terms of something familiar. ... If you will simply admit that maybe [Nature] does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possible avoid it, "But how can it be like that?" because you will get 'down the drain', into a blind alley from which nobody has escaped. Nobody knows how it can be like that.

Richard P. Feynman

If you thought that science was certain - well, that is just an error on your part.

Richard Dawkins

Cheetah genes cooperate with cheetah genes but not with camel genes, and vice versa. This is not because cheetah genes, even in the most poetic sense, see any virtue in the preservation of the cheetah species. They are not working to save the cheetah from extinction like some molecular World Wildlife Fund.

Richard Whately

To teach one who has no curiosity to learn, is to sow a field without ploughing it.

Frank Wood

He was the kind of guy, when things were down, he brightened them up. He was happy-go-lucky ... and that light shone around him all the time.

Richard Posner

The Constitution has to be interpreted loosely, otherwise it becomes a straitjacket. You can't interpret it literally. You can pretend to, and go digging around in 18th Century dictionaries to figure out what 'cruel and unusual punishment' meant or what the 'right to bear arms' meant, but that is all fake really. The Constitution has to be interpreted in light of modern needs, and that's what they (the strict interpreters) end up doing in spite of all their investigations.

William Jennings Bryan

The money power denounces, as public enemies, all who question its methods or throw light upon its crimes.

Virginia Woolf

She dares me to pour myself out like a living waterfall. She dares me to enter the soul that is more than my own; she extinguishes fear in mere seconds. She lets light come through.

Woody Allen

What advice would I give the average homeowner to protect himself against burglars? Well, the first thing is to keep a light on in the house when you go out. It must be at least a sixty-watt bulb; anything less and the burglar will ransack the house, out of contempt for the wattage.

Woody Allen

When you are dead, it is hard to find the light switch.

William Wordsworth

A light to guide, a rod To check the erring, and reprove.

Robert Delaunay

Light comes to us by the sensibility. Without visual sensibility there is no light, no movement.

Robert Delaunay

Impressionism; it is the birth of Light in painting.
